Finally, according to the procedure of example 1, the end of the suspension plate 1-4 remote from the first support plate 1-2 and the second support plate 1-3 are fixed using suspension plate fixing members.
As can be seen from the above using process, the power transmission cable suspension distance limiting device of this embodiment 4 can enable the power transmission cable 100 to be compressed by the torsion spring pressing buckle 5 on the basis of embodiment 1, so as to prevent the insulating suspension mechanism 1 from sliding on the power transmission cable 100, thereby improving the stability of the insulating suspension mechanism 1 and the power transmission cable 100 being installed together.
In order to improve the friction force between the torsion spring pressing buckle 5 and the power transmission cable 100 to improve the stability of the torsion spring pressing buckle 5 pressing on the power transmission cable 100, an anti-slip sleeve (not shown in the figure) is sleeved on the torsion spring pressing buckle 5, and the anti-slip sleeve is a rubber sleeve.
Example 5:
in order to reduce the influence of construction work (e.g., building construction work) on the daily life of people, the current construction is mostly arranged at night, the visibility is lower during the night construction, and a driver operating large equipment cannot see the positions of the power transmission cable 100 and the insulating distance limiting rod 2 at night, so that the driver operating the large equipment cannot control the distance from the power transmission cable 100, the power transmission cable 100 is easily damaged by external force such as the large equipment, and the stable operation of the power transmission cable 100 cannot be guaranteed.
Therefore, as shown in fig. 9, in the power transmission cable suspension distance limiting device according to embodiment 5, a warning lamp is provided on the insulating distance limiting rod 2. Preferably, the warning lamp adopts a solar flashlight 6, and the solar flashlight 6 is fixed on the insulating distance-limiting rod 2 through a fastener.
Through setting up solar energy flash light 6, the driver that can conveniently operate the large-scale equipment is when the construction at night, notice the solar energy flash light 6 on the insulating range rod 2 of transmission cable 100 below, avoid because night visibility is low, make the driver of operation large-scale equipment can't see insulating range rod 2 and can't be the far and near of control distance from transmission cable 100, thereby avoid taking place to make transmission cable 100 by the accident of external force destruction such as large-scale equipment because of seeing insulating range rod 2 night, the steady operation of transmission cable 100 has been ensured.
Therefore, the power transmission cable suspension distance limiting device of the embodiment 5 is more suitable for being used at night.
In addition, through using solar energy flash light 6, can use this green clean energy of solar energy, accord with the situation of current green construction, the energy saving.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
